A betting strategy (also known as betting system) is a structured approach to gambling, in the attempt to produce a profit. To be successful, the system must change the house edge into a player advantage — which is impossible for pure games of probability with fixed odds, akin to a perpetual motion machine. [ 1 ]
A session is a sequence of consecutive wagers made until 1 unit of profit is won. [2] Each session begins by betting 1 unit, and ends by winning 1 unit of profit. If the gambler loses, the session continues and the bet is repeated. Each time the gambler wins the game following a lost game, the bet is increased by 1 unit.
So a bet on a 3-point underdog at +3 will become a bet at +9.5 points, and for favorites, it will change a 3-point favorite at −3 to +3.5 points. Although the rules to win his bet are the same as a parlay, he is paid less than a regular parlay due to the increased odds of winning. If bets. An if bet consists of at least two straight bets ...

Example of the optimal Kelly betting fraction, versus expected return of other fractional bets. In probability theory, the Kelly criterion (or Kelly strategy or Kelly bet) is a formula for sizing a sequence of bets by maximizing the long-term expected value of the logarithm of wealth, which is equivalent to maximizing the long-term expected geometric growth rate.
